CABLEVJAY.

Application filed January 16, 1913.

ful Iinurovcments in Cableways, of which the following is a specification.

My invention relates to cableways, and particularly to means whereby side stralns may be taken off of cableways, thus enabling them to be used for hauling in loads from points removed some distance at the side, or for pulling laterally thereof without producing undue strains upon the cableways.

The obj ect of my invention is to improve cableways so that they may be strengthened against such side strains without complicating them too much, thus enabling them to do work which could not otherwise be done.

My invention comprises the novel parts and combinations of parts which will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawings 1 have shown my invention in the form which is new preferred by me.

Figure 1 shows, in elevation, the plan of a cableway having my invention embodied therein. Fig. 2 is a plan showing the same thing. Fig. 3 is a side view and Eig. 4 an edge view of a special form of sheave and sheave frame, which is used to advantage for the snubbing line. Fig. 5 is a side elevation of a carriage showing the cotiperation therewith of said special sheave and frame.

I have herein shown, and will describe, my invention as employed upon a cableway used for logging, although it is to be understood that a cableway equipped with my invention may be employed for any purpose to which it is found suited.

In logging with cableways, it is found that the limit of their ability to get logs located laterally of the trackway cables, is quickly reached, as to draw them into a point beneath the cableway brings a side strain upon the cableway much greater than is required for any other work which is required of it. One reason for this is that the trackway cables are not required to take the entire strain of pulling the logs over the ground, this being communicated to them only in part; and also because, while Working close under the cableway, the front end of the log is lifted partially or entirely oil Specification of Letters Patent.

of the ground, which enables it to ride easily over any obstruction, and also reduces the frictional resistance to its forward movement. in pulling in from a point laterally removed from the cableway, it soon becomes a straight drag over the ground, with all the obstructions which are necessarily associated with this. With the ordinary cableway the trackway cables must take all this strain. By my invention I provide a snubbing line which may be applied to the haul line to take all this side strain, so that a haul from the side will place no extra strain upon the trackway cables, thus permitting hauling from the sides as far as desired and making these hauls as heavy as the haul line will stand.

In the drawings 1 represents the trackway cable,2the haul line and3 the haul-back line. These may be disposed and operated in any desired and suitable manner. I have shown the haul-back line as extending first to the tail mast 12, about a pulley or sheave thence about a pulley 31 on the carriage 8, thence to a distant and movable, out-haul sheave 32, and then to a connection with the end of the haul line 2. The haul line passes about a sheave 2 0 on the carriage and thence laterally, or in any direction from which it is desired to bring a log. Upon this haul line, whenever it is desired to haul a log of any size from any considerable lateral distance, I place a sheave to which a snubbing line is secured. If properly handled, any ordinary sheave may be used with considerable success, but I prefer to use a special type of sheave, having a frame which prevents catching in the carriage frame. Such a sheave and frame is shown in Figs. 3 and i. This sheave is placed directly upon the hauling line beneath the carriage, that is, between the carriage and the end of the haul line. The haul line passes over the sheave 20 on the carriage and then through the snubbing sheave 5.

Sheave 5 is a provided with an eye or equivalent means 53, for the attachment of the snubbing line 4, and with a contact head or flange 51, having suflicient lateral extent that it may be depended upon to engage the carriage frame without entering between the sides thereof to become caught. I have shown this contact head or flange as curved, whereby it presents more nearly a perpendicular surface to the carriage frame, whatever the angle assumed by diilerence in din reotion of the snubbing line and the haul line.

In use, after the haul line has been attached to a log, located at any distance much increased. Instead of being able to" cover a strip of not more than 150 feet wide, a strip of six to eight hundred feet may be covered, at one setting. Its capacity is further increased by being able to haul larger logs than would be possible without the use of the snubbing line.

What I claim as my invention is 1. The combination with a cableway and a hauling line, of a snubbing line having traveling engagement with the haul line between the cableway and the load.

2. In a cableway, the combination with the trackway cables, a carriage thereon hav ing a guide for a haul line, a haul line passing over said guide, and a snubbing line having traveling engagement with the haul line beyond the carriage.

3. The combination with a cableway having a carriage thereon and a cable guide upon the carriage, a haul line passing over said guide on the carriage, a sheave upon the haul line beyond said guide, and a snubbing line secured to said sheave.

4. The combination with a cableway comprising a trackway cable, a carriage movable upon said trackway, a guide sheave on the carriage adapted to receive a haul line, a back-haul line connected with the carriage by a loop extending from the vicinity of the tail mast, a guide for said back-haul line carried by the carriage, a distant and movable guide for the back-haul line between the carriage and the end of said line, a haul line passingover its guide on the carriage, and a snubbing line having a running engagement with the haul line between the carriage and the end of said line.

5. The combination with a cableway having a haul line, of a snubbing line provided at one end with means for a running engagement with the haul line, the other end of the snubbing line being free for temporary engagement with any convenient snubbing object.

6. A snubbing device for use with cableways comprising a sheave adapted to be placed upon the haul line, and a snubbing line secured to said sheave.

7. A logging cableway comprising trackway cables, a carriage thereon, a haul line passing througa the carriage, two distant guides for the haul-back line, one of which is adjustable in position, a haul-back line passing through said guides and through a guide upon the carriage between said distant guides, and a snubbing line having free running engagement with the haul line beyond the carriage.

In testimony whereof I have hereunto aflixed my signature at Oso, Snohomish county, lVashington, this 9th day of January, 1918.
